"""
Command line tool for showing the result of a simple python expression.

Some common modules are imported for you (e.g. math, datetime, pprint, etc.).

Exceptions are caught and printed, instead of showing a full traceback.

Examples:
    $ py "2+2"
    2+2 -> 4

    $ py "1/0"
    1/0 -> ZeroDivisionError('integer division or modulo by zero',)

    $ py "map(lambda x: x**2, range(10))"
    map(lambda x: x**2, range(10)) -> [0, 1, 4, 9, 16, 25, 36, 49, 64, 81]

    $ py "math.sqrt(81)"
    math.sqrt(81) -> 9.0

    $ py "glob.glob('*.py')"
    glob.glob('*.py') -> ['called_from.py', 'hmm.py', 'mc.py', 'xx.py', 'yvfc.py']

    $ py "os.getcwd()"
    os.getcwd() -> '/home/steve'
